firebase - 如何知道哪个registration_id是坏的/过期的/已删除的

Question

所以我正在将通知批量推送到多个设备。如果设备 GFCM token 不在 firebase 中，我想从我的数据库中删除它们。

测试请求:

{"registration_ids": ["fznIum-OIL0:APA91bE9n6gxqVEB3hR0On_TZqH_cOOO7rFyLE5MYbvKXUX3737IonXquZRoHeY1UJf20G4nrahz35p80X8PAPouviYvXgtekAzeDFuwaWyiPI1sFlN1d1wGp5OulXv9wUzHyegeZiih","dsasadadsasdasdasdasdefs","fjb0qTB9ACI:APA91bHvx0pSlq-NuQz-bU70DhL7BXAcd-DqT9YT0ZjYw7R_pkBmr8oe6XdNw8IPlU67d-rXMfRY3mybaO7K5GHo_NH7G-Ya1Ae2xxJP1JIbuuSYomz31y_MPQijFK8w-bZXQ26SWE09"],
"notification":{
    "body":"Yoou have a new message from Alice"}}

和回应:

{
  "multicast_id": 7971310728176484096,
  "success": 1,
  "failure": 2,
  "canonical_ids": 0,
  "results": [
    {
      "error": "NotRegistered"
    },
    {
      "error": "InvalidRegistration"
    },
    {
      "message_id": "0:1481547993513035%4f9c20964f9c2096"
    }
  ]
}

如何检测哪些registration_id是错误的/未注册的？

谢谢!

好吧，我想我已经明白了。

“results”:按照您在registration_ids中指定的顺序返回响应/错误
